A 150 g ball is thrown towards a wall with a speed of 6.5 m/s. If bounces off the wall with a speed of 3.5 m/s, determine the impulse provided by the wall.

Answer:1500Ns

Explanation:

Mass (m) = 150g

Initial velocity (u) = -6.5m/s

Final velocity (v) = 3.5m/s

Impulse=change in momentum

Change in momentum=m (v-u)

Change in momentum=150 (3.5 - (-6.5))

Change in momentum=150 (3.5+6.5)

Change in momentum=150 (10)

Change in momentum=1500Ns
